230 LOXGIOOBNIA. [f.<'J)(uriJM. 



LEPTURINA. 



This tribe is represented in Europe by just one hundred species ; the 

 number of genera is about twenty, but some authors include Anoplodi'ra 

 and Strangalia, and even Grammo^tera, under Lejifura, and Pac////fa 

 is differently divided ; these are in this work regarded as distinct, but 

 their distinctions are, perhaps, hardly sufficient to warrant their separa- 

 tion; we possess twenty-five species as British, but two or three of 

 these are somewhat doubtfully indigenous. 



I. Prosternal process reaching hinder edge of anterior 

 coxse ; posterior tarsi with the fire*, joint broad and not 

 compressed ; antenna; comparatively short or very short . KHAGIUM, F. 



II. Prosternal process very short, not nearly reaching 

 hinder edge of auterior coxae ; posterior tarsi with the 



first joint narrow and compressed ; antennae long. 

 i. First joint of posterior tarsi with the usual brush of 

 hair beneath. 



1. Thorax armed at sides with a distinct and large 

 tubercle ; fourth joint of antennae half as long as 



fifth TOXOTCS, Serv. 



2. Thorax without, or with a very indistinct, tubercle 

 at sides ; fourth joint of antenna) nearly as long as 



fifth PACUYTA, iSVvi'. 



ii. First joint of posterior tarsi, and usually the second 

 also, without a brush of hair beneath. 



1. Thorax not produced into a spiue at posterior 



angles. 



A. Elytra almost parallel-sided, with antennae about 



as long as body ANOPI/ODBHA, Muls. 



B. Elytra with the apex plainly narrower than the 

 base, as a rule, gradually narrowed from base to 



apex,* with the antennae shorter than body LEPTUHA, L. 



2. Thorax produced into a spine at posterior angles. 



A. Elytra narrowed from base to pex, usually 

 emarginate at apex, with the exterior angles imi- 



cronate STRANGALIA, Strv. 



B. Elytra almost parallel-sided, not emarginate at 



apex GBAMMOPTEBA, Sertn 



RHAGXUltX, Fabricius. (Stenocorus, Geoffrey.) 



I have followed Thomson in retaining the old name for this genus, 

 although Geoffroy's name is adopted by the majority of modern writers ; 

 the genus contains about eight species, which are confined to the 

 Northern Hemisphere, with the exception of one that has been described 

 from the Cape of Good Hope ; they may be known by their com- 

 paratively short or very short antennae, which in two species do not 

 reach much beyond the base of the thorax, but in the third species are 

 longer, and by the formation of the prosternal process ; the eyes are 



* In the female of L. livida the elytra are subparallel until a little before apex; 

 the antenna-, however, are considerably shorter than the body.
